Myanmar Rejection confirmation

After talking with the embassy in Hanoi and VTE and getting odd looks about taking the bike in, I did cross today on foot at Mae Sai and according to the customs persons there, it is possible but you need 10 people in a group and have a guide. It takes a long time to set up and he told me he is unsure about who in the central gov't to call since they all moved out of Yangoon.
